Insecticidal pyrimidinyl aryl hyrdrazones

ABSTRACT

Pyrimidinyl aryl hydrazones are effective at controlling insects.

BACKGROUND OF THE INVENTION

This application claims the benefit of U.S. Provisional Application Ser. No. 60/998,200 filed on Oct. 9, 2007. The present invention concerns novel pyrimidinyl aryl hydrazones and their use in controlling insects, particularly lepidoptera and/or coleoptera. This invention also includes new synthetic procedures, intermediates for preparing the compounds, pesticide compositions containing the compounds, and methods of controlling insects using the compounds.

There is an acute need for new insecticides and acaricides. Insects and mites are developing resistance to the insecticides and acaricides in current use. At least 400 species of arthropods are resistant to one or more insecticides. The development of resistance to some of the older insecticides, such as DDT, the carbamates, and the organophosphates, is well known. But resistance has even developed to some of the newer pyrethroid insecticides and acaricides. Therefore a need exists for new insecticides and acaricides, and particularly for compounds that have new or atypical modes of action.

The present invention provides novel compounds with broad-spectrum activity against insects, particularly lepidoptera and/or coleoptera.

Synthesis of a compound of the formula (I) (where Z=CH) has been described in the literature (“Preparation of Pyrimidine Compounds as mixed Lymphocyte Reaction (MLR) inhibitors” Tsuruoka, Hiroyuki; Matsuda, Akihisa; Sugano, Yuichi; Tatsuta, Toru, WO2005037801).

Also, compounds of the formula (I) can be synthesized from commercially available 2,4,6-trihalopyrimidine (II) by stepwise addition of nucleophiles. More particularly, the compounds of the formula (I) can be synthesized according to the chemical processes outlined below.

General Method 1

In the first step, a 2,4,6-trihalopyrimidine of the formula (II) (where W═Cl or F; and L=H, F, Cl) is condensed with one equivalent of an aryl amine of the formula (III) in the presence of a base in a polar aprotic solvent to afford the mono aminated regioisomeric pyrimidine derivatives of the formula (IV) and (V) (Scheme 1). Other functional groups such as alkyl (or aryl) sulphonyl can be employed in place of W to effect this transformation. Trialkylamine such as diisopropylethylamine and inorganic bases such as potassium carbonate are the preferred bases for coupling, however, other organic or inorganic bases can be used. Although dioxane or tetrahydrofuran (THF) or dimethyl formamide (DMF) are used as the preferred solvents, other polar aprotic solvents can also be used to carry out this transformation.

In the second step, the 2-arylamino pyrimidines of the formula (IV) (where W═Cl or F and L=H, F, Cl prepared according to Scheme 1) are reacted with excess hydrazine RNHNH₂ in an aprotic solvent to afford the compounds of the formula (VI) (Scheme 2). Although dioxane, THF or DMF are used as the preferred solvents, other polar aprotic solvents can be used to carry out this transformation.

Similarly, 4-arylamino-2,6-dihaloropyrimidines of the formula (V) (where W═Cl or F; and L=H, F, Cl) are reacted with excess hydrazine RNHNH₂ in an aprotic solvent such as THF or dioxane or DMF to afford the compounds of the formula (VII) (Scheme 3). Although dioxane or THF or DMF are used as the preferred solvents, other polar aprotic solvents can also be used to carryout this transformation.

In the last step, the hydrazino derivative of the formula (VI) or (VII) are reacted with an aryl aldehyde of the formula (VIII) in a solvent such ethanol or a mixture of ethanol and another solvent such as THF or dichloromethane to give the compounds of the formula (I) (Scheme 4).

General Method 2

In Step 1 of this method, compounds of the formula (IV) (where W═Cl, F; L and R are as defined above) are reacted with an amine or (thio)alkoxy nucleophile (QH:) in the presence of a solvent to provide the compounds of the formula (IX) (Scheme 5). In Step 2, compounds of the formula (IX) are reacted with hydrazine of the formula RNHNH₂ in the presence of a base and a solvent to give the corresponding compounds of the formula (X) (Scheme 5). In step 3, compounds of the formula (X) are treated with aldehydes of the formula (VIII) to give the compounds of the formula (I). Ethanol, dioxane, THF and DMF are preferred solvents although other solvents can be used to carryout this transformation.

Similarly, compounds of the formula (V), prepared according to Scheme 1 (where W═Cl, F), are reacted with an amine or alkoxy nucleophile (QH) in the presence of a base and solvent to provide the regioisomeric compounds of the formula (XI) and (XII) (Scheme 6, Step-1). Compounds of the formula (XI) and (XII) are reacted with hydrazine RNHNH₂ in the presence of a solvent to give the corresponding compounds of the formula (XIII) and (XIV), respectively (Scheme 6, Step-2). In step 3, compounds of the formula (XIII) and (XIV) are treated with aldehydes of the formula (VIII) to give the compounds of the formula (I). Ethanol, dioxane, THF and DMF are preferred solvents although other solvents can be used to carry out these transformations.

General Method 3

In this method a halopyrimidine intermediate of the formula (XV) [where U=(halo)alkyl and W═H, Cl, F, S(O)_(n)R₂ (n=0-2)] is condensed with one equivalent of an aryl amine of the formula (III) in the presence of a base in a polar aprotic solvent to afford the mono aminated regioisomeric pyrimidine derivatives of the formula (XVI) and (XVII) (Scheme 7). Trialkylamines such as diisopropyl-ethylamine and inorganic bases such as potassium carbonate are the preferred bases for this coupling, however, other organic or inorganic bases can be used. Although dioxane or THF or DMF are used as the preferred solvents, other polar aprotic solvents can also be used to carryout this transformation.

The arylamino pyrimidines of the formula (XVI) and (XVII) are reacted, individually, with hydrazine RNHNH₂ in the presence of a solvent to give the corresponding compounds of the formula (XVIII) and (XIX), respectively (Scheme 8). Compounds of the formula (XVIII) and (XIX) are treated, individually, with aldehydes of the formula (VIII) in a solvent to give the compounds of the formula (I) (Scheme 8). Ethanol, dioxane, THF and DMF are preferred solvents although other solvents can be used to carry out these transformations.

Insecticide Utility

The compounds of the invention are useful for the control of invertebrates including insects. Therefore, the present invention also is directed to a method for inhibiting an insect which comprises applying an insect-inhibiting amount of a compound of formula (I) to a locus of the insect, to the area to be protected, or directly on the insect to be controlled. The compounds of the invention may also be used to control other invertebrate pests such as mites and nematodes.

The “locus” of insects or other pests is a term used herein to refer to the environment in which the insects or other pests live or where their eggs are present, including the air surrounding them, the food they eat, or objects which they contact. For example, insects which eat, damage or contact edible, commodity, ornamental, turf or pasture plants can be controlled by applying the active compounds to the seed of the plant before planting, to the seedling, or cutting which is planted, the leaves, stems, fruits, grain, and/or roots, or to the soil or other growth medium before or after the crop is planted. Protection of these plants against virus, fungus or bacterium diseases may also be achieved indirectly through controlling sap-feeding pests such as whitefly, plant hopper, aphid and spider mite. Such plants include those which are bred through conventional approaches and which are genetically modified using modern biotechnology to gain insect-resistant, herbicide-resistant, nutrition-enhancement, and/or any other beneficial traits.

It is contemplated that the compounds might also be useful to protect textiles, paper, stored grain, seeds and other foodstuffs, houses and other buildings which may be occupied by humans and/or companion, farm, ranch, zoo, or other animals, by applying an active compound to or near such objects. Domesticated animals, buildings or human beings might be protected with the compounds by controlling invertebrate and/or nematode pests that are parasitic or are capable of transmitting infectious diseases. Such pests include, for example, chiggers, ticks, lice, mosquitoes, flies, fleas and heartworms. Nonagronomic applications also include invertebrate pest control in forests, in yards, along road sides and railroad right of way.

The term “inhibiting an insect” refers to a decrease in the numbers of living insects, or a decrease in the number of viable insect eggs. The extent of reduction accomplished by a compound depends, of course, upon the application rate of the compound, the particular compound used, and the target insect species. At least an inactivating amount should be used. The term “insect-inactivating amount” is used to describe the amount, which is sufficient to cause a measurable reduction in the treated insect population. Generally an amount in the range from about 1 to about 1000 ppm by weight active compound is used. For example, insects or other pests which can be inhibited include, but are not limited to:

Compositions

The compounds of this invention are applied in the form of compositions which are important embodiments of the invention, and which comprise a compound of this invention and a phytologically-acceptable inert carrier. Control of the pests is achieved by applying compounds of the invention in forms of sprays, topical treatment, gels, seed coatings, microcapsulations, systemic uptake, baits, eartags, boluses, foggers, fumigants aerosols, dusts and many others. The compositions are either concentrated solid or liquid formulations which are dispersed in water for application, or are dust or granular formulations which are applied without further treatment. The compositions are prepared according to procedures and formulae which are conventional in the agricultural chemical art, but which are novel and important because of the presence therein of the compounds of this invention. Some description of the formulation of the compositions will be given, however, to assure that agricultural chemists can readily prepare any desired composition.

The dispersions in which the compounds are applied are most often aqueous suspensions or emulsions prepared from concentrated formulations of the compounds. Such water-soluble, water-suspendable or emulsifiable formulations are either solids, usually known as wettable powders, or liquids usually known as emulsifiable concentrates or aqueous suspensions. Wettable powders, which may be compacted to form water dispersible granules, comprise an intimate mixture of the active compound, an inert carrier, and surfactants. The concentration of the active compound is usually from about 10% to about 90% by weight. The inert carrier is usually chosen from among the attapulgite clays, the montmorillonite clays, the diatomaceous earths, or the purified silicates. Effective surfactants, comprising from about 0.5% to about 10% of the wettable powder, are found among the sulfonated lignins, the condensed naphthalenesulfonates, the naphthalenesulfonates, the alkylbenzenesulfonates, the alkyl sulfates, and nonionic surfactants such as ethylene oxide adducts of alkyl phenols.

Emulsifiable concentrates of the compounds comprise a convenient concentration of a compound, such as from about 50 to about 500 grams per liter of liquid, equivalent to about 10% to about 50%, dissolved in an inert carrier which is either a water miscible solvent or a mixture of water-immiscible organic solvent and emulsifiers. Useful organic solvents include aromatics, especially the xylenes, and the petroleum fractions, especially the high-boiling naphthalenic and olefinic portions of petroleum such as heavy aromatic naphtha. Other organic solvents may also be used, such as the terpenic solvents including rosin derivatives, aliphatic ketones such as cyclohexanone, and complex alcohols such as 2-ethoxyethanol. Suitable emulsifiers for emulsifiable concentrates are chosen from conventional anionic and/or nonionic surfactants, such as those discussed above.

Aqueous suspensions comprise suspensions of water-insoluble compounds of this invention, dispersed in an aqueous vehicle at a concentration in the range from about 5% to about 50% by weight. Suspensions are prepared by finely grinding the compound, and vigorously mixing it into a vehicle comprised of water and surfactants chosen from the same types discussed above. Inert ingredients, such as inorganic salts and synthetic or natural gums, may also be added, to increase the density and viscosity of the aqueous vehicle. It is often most effective to grind and mix the compound at the same time by preparing the aqueous mixture, and homogenizing it in an implement such as a sand mill, ball mill, or piston-type homogenizer.

The compounds may also be applied as granular compositions, which are particularly useful for applications to the soil. Granular compositions usually contain from about 0.5% to about 10% by weight of the compound, dispersed in an inert carrier which consists entirely or in large part of clay or a similar inexpensive substance. Such compositions are usually prepared by dissolving the compound in a suitable solvent and applying it to a granular carrier which has been pre-formed to the appropriate particle size, in the range of from about 0.5 to 3 mm. Such compositions may also be formulated by making a dough or paste of the carrier and compound and crushing and drying to obtain the desired granular particle size.

Dusts containing the compounds are prepared simply by intimately mixing the compound in powdered form with a suitable dusty agricultural carrier, such as kaolin clay, ground volcanic rock, and the like. Dusts can suitably contain from about 1% to about 10% of the compound.

It is equally practical, when desirable for any reason, to apply the compound in the form of a solution in an appropriate organic solvent, usually a bland petroleum oil, such as the spray oils, which are widely used in agricultural chemistry.

Insecticides and acaricides are generally applied in the form of a dispersion of the active ingredient in a liquid carrier. It is conventional to refer to application rates in terms of the concentration of active ingredient in the carrier. The most widely used carrier is water.

The compounds of the invention can also be applied in the form of an aerosol composition. In such compositions the active compound is dissolved or dispersed in an inert carrier, which is a pressure-generating propellant mixture. The aerosol composition is packaged in a container from which the mixture is dispensed through an atomizing valve. Propellant mixtures comprise either low-boiling halocarbons, which may be mixed with organic solvents, or aqueous suspensions pressurized with inert gases or gaseous hydrocarbons.

The actual amount of compound to be applied to loci of insects and mites is not critical and can readily be determined by those skilled in the art in view of the examples above. In general, concentrations from 10 ppm to 5000 ppm by weight of compound are expected to provide good control. With many of the compounds, concentrations from 100 to 1500 ppm will suffice.

The locus to which a compound is applied can be any locus inhabited by an insect or mite, for example, vegetable crops, fruit and nut trees, grape vines, ornamental plants, domesticated animals, the interior or exterior surfaces of buildings, and the soil around buildings.

Because of the unique ability of insect eggs to resist toxicant action, repeated applications may be desirable to control newly emerged larvae, as is true of other known insecticides and acaricides.

Systemic movement of compounds of the invention in plants may be utilized to control pests on one portion of the plant by applying the compounds to a different portion of it. For example, control of foliar-feeding insects can be controlled by drip irrigation or furrow application, or by treating the seed before planting. Seed treatment can be applied to all types of seeds, including those from which plants genetically transformed to express specialized traits will germinate. Representative examples include those expressing proteins toxic to invertebrate pests, such as Bacillus thuringiensis or other insecticidal proteins, those expressing herbicide resistance, such as “Roundup Ready®” seed, or those with “stacked” foreign genes expressing insecticidal proteins, herbicide resistance, nutrition-enhancement and/or any other beneficial traits.

An insecticidal bait composition consisting of compounds of the present invention and attractants and/or feeding stimulants may be used to increase efficacy of the insecticides against insect pest in a device such as trap, bait station, and the like. The bait compostion is usually a solid, semi-solid (including gel) or liquid bait matrix including the stimulants and one or more non-microencapsulated or microencapsulated insecticides in an amount effective to act as kill agents.

The compounds of the present invention (Formula I) are often applied in conjunction with one or more other insecticides or fungicides or herbicides to obtain control of a wider variety of pests diseases and weeds. When used in conjunction with other insecticides or fungicides or herbicides, the presently claimed compounds can be formulated with the other insecticides or fungicides or herbicide, tank mixed with the other insecticides or fungicides or herbicides, or applied sequentially with the other insecticides or fungicides or herbicides.
